SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 655,543, dated August 7, 1900.

Application filed January 4, 1900. Serial No. 355. (No model.)

To aZZ whom it may concern:

Be it known that I, J OHN BOHLEN, a citizen of the United States, and a resident of Big Rapids, in the county, of Mecosta and State of Michigan, have'invented a new and Improved Sash-Holder, of which the following is a full, clear, and exact description.

The object of, my invention is to provide a simple and durable form of sash holder adapted to be used in connection with a rack of any description and to so construct the device that it may be locked in or out of engagement with the rack and operated in such manner that the window to which it is applied may be as conveniently operated when the latch is out of engagement with the rack as if the rack were not present.

Another object of the invention is to provide a latch which can be applied with good results to car, coach, or other vehicle windowsashes as well as to the window-sashes of buildings.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Referenceis to be had to the accom panying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a portion of a window sash and frame and likewise a perspective view of the improvement applied to the sash. Fig. 2 is a rear View of the improved latch, the back plate having been removed. Fig. 3 is a longitudinal section on the line 3 3 of Fig. 2. Fig. 4 is a detail perspective view of the bolt operating arm. Fig. 5 is a detail perspective view of the bolt. Fig. 6 is a detail perspective View of the rack used in connection with the device, and Fig. 7 is a detail perspective view of the keeper for the bolt-operating arm.

A represents a portion of a window-frame, B a portion of a sash, and O the casing for the improved latch, which is secured by screws or otherwise to the upright rail 10 of the sash 13. This casing is provided with a top and with a bottom flange 0, through which the screws are passed, and a back 0, although the back may be omitted, if desired. The body of the casing is provided near the top at its inner side with a small opening 11 and at the opposite side with an opposing and larger opening 12. The smaller opening 11 is adapted to receive the stem 13 of a bolt D, the head 14 whereof when the bolt is sprung or is in locking position extends out throughthe opening 12 in the easing." The head 14 of the bolt at its outer or working end ispreferably provided with beveled or rounded edges 15, as shown in Fig.5. The head 14 of the bolt D, as is also shown in Fig. 5, is provided with an angular exten sion 16'at its bottom portion, the horizontal member 16 whereof is carried beneath the stem 13, and the vertical member 16 of the said extension has its outer face or the face which is nearest the window-sash provided with an inclined or rounded surface 17, while at the outer end of the horizontal member 16 of. the bolt extension 16 a lug 18 is formed upon one side face, having an inclined or rounded edge which faces the inclined or rounded surface 17 of the saidex'tension, as is shown in Figs. 2 and 5.

The head 14 of the bolt D is normally forced out through the casing through the medium of a spring 19, coiled around the stem 13 of the bolt within the casing. In connection with the bolt D, I employ an operating-arm E, (shown in detail in Fig. 4,) and this operating-arm consists of a shank or body 20 and a head 21, which extends from the upper portion of the shank, the said head having an in clined surface 22, adapted for engagement with the inclined surface of the projection 18 from the extension of the bolt D. This projection or lug 18 on the bolt serves to limit the outward movement of the bolt-head 14, since when the head reaches its full outward throw the lug or projection 18 engages with a side wall of the body, as shown in Fig. 2. Upon what maybe termed its front face the operating-arm E is provided with an offset 23, having an inclined edge, as is shown in Fig. 74:, and the said operating-arm is f urt-her provided with a recess 23 in its opposite face adjacent to the head, the offset 23 being located on the arm where the head connects with the shank. A'knob 25 is also formed at the lower end of the shank of the operatingarm. The operating-arm is adapted to enter a tubular offset 25 formed in the lower flange of the casing and in communication with the interior of the body of the casing, as shown in Fig. 2. This tubular offset receives the shank 20 of the operating-arm, and

when the said operating-arm is in position its the bolt D, the inclined surface of the ofiset' 23 facing the inclined surface 17 of the said extension, so that when the shank of the bolt is pressed upward the inclined surface of the olfset 23 will be brought in positive engagewith the inclined surface 17 of the extension of the bolt, and will force the bolt inward,

contracting the spring 19 when the said spring is employed. The end of the shank at which the knob 25 is attached extends beyond the bottom of the casing, and when the operating-arm E is in position in the casing the inclined surface 22 of the head of the said operating-arm is in engagement with the inclined surface on the lug 18 of the bolt D, as shown in Fig. 2. hen the head of the bolt is in its outer position, (shown in Fig. 2,) the recess 23 in thestem of the operating-arm is opposite a recess 24:, formed in the inner face of the lower flange c of the casing, as is also shown in Fig. 2. This recess 2% is adapted to receive a latch F, which latch is held to slide in the recess 24, and consists of a plate26,

having a slot 27 made therein, through which a bolt 28 is passed and through the lower flange c of the casing, and at the inner end of the plate 26 a lip 29 is formed, which when the bolt-head 14 is in its outer position is adapted to enter the recess 23 in the operating-arm E, as shown in Fig. 2, thereby preventing the operating-arm from being moved upward or downward until released from the latch. The latch is operated through the medium of a flange 31, which is formed atits outer end. \Vhen the head 14 of the bolt D has been drawn within the casing, the bolthead is held in this position by reason of the lip of the latch engaging a shoulder 30 on the stem of the operating-arm below the recess 23. A second shoulder 31 is formed where the head of the operating-arm connects with the shank, and this shoulder limits the downward movement of the operating-arm in the casing.

In connection with the latch just described a rack G is employed. This rack is adapted to be attached to the outer face of a stopbead A of the window-frame, as shown in Fig. 1, and the said rack consists of a plate or bar having a longitudinal recess 32 in its front face, as shown in Fig. 6, and openings 33 in the back vertical wall of the said recess, which openings 33 are adapted to receive the head of the bolt D when the window has been raised or closed and it is desired to lock or support the window inadjusted position.

In the operation of the device, when the spring 19 is used, if the bolt is in engagement with the rack G the latch F is drawn out from engagement with the operating-arm. The operating-arm is then forced upward, which action draws the head of the bolt inward in the manner described, and the bolt may be held in this position by carrying the latch F inward to engage with the shoulder 30, at which time both hands of the operator will be free to manipulate the window-sash. When the window-sash has been raised as far as desired, upon drawing the latch F outward the spring 19 will act and will force the bolt-head 14 out into the most convenient opening 33 in the rack. G, and the window-sash may be held in such position by carrying the latch F inward, so that its lip 29 will enter the reces's 23 in the shank of the operating-arm. The spring 19, although desirable, is not absolutely necessary, since if it be omitted and the bolt-head is drawn within the casing by the upward movement of the operating-arm the bolt-head may be forced outward again when the operating-arm is drawn downward by reason of the contact between the inclined surface of the head of the operatingarm and the inclined surface on the lug 18, carried by the bolt.

I desire it to be understood that the parts of the device may be so assembled that a core will not be necessary in its manufacture and that the character of the rack maybe changed.

Having thus described my invent-ion, I claim as new and desire to secure by Letters Patent 1. The combination of a casing, a bolt mounted to slide therein and provided-with two inclined surfaces facing respectively toward the outer and the inner end of the bolt, and an operating-arm having sliding movementin the casing and provided on one side with an inclined su rfaee facing toward one end of the arm and arranged for contact with one inclined surface of the bolt, while on the other side the operating-arm is provided with a se'cond inclined surface facing toward the other end of the arm and arranged for contact with the second inclined surface of the bolt.

2. The combination of a casing, a bolt mounted to slide therein and provided with opposinginclinedsurfacesfacingrespectively toward the inner and the outer end of the bolt, an operating-arm having sliding movementbetween the said opposing inclined surfaces of the bolt, and provided on opposite sides, with inclined surfaces, each arranged to engage one of the inclined surfaces of the bolt, and a latch arranged to lock the said operating-arm.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN BOHLVEN.
